Interesting aircraft related comment Cobber. However did you know, that the requirements to design, build, and fly your own aircraft are actually far less restrictive than it is to do the same with a car?

Airplanes are actually easier. They have a special category (like the ICV) but unlike the ICV, many or the rules and requirements are waived on the basis that they are personal use craft, and not for fare paying passengers or commercial work.
